Light weight structural is a young and great vitality of steel structure system, has been widely used in industrial and agricultural, commercial, service construction, such as office buildings, villas, warehouses, sports stadiums, entertainment,tourism, construction and low, multilayer residential buildings, light steel frame and other fields.

Determine the structure of steel and light steel structure, we can with some data comprehensive consideration and judgment:

1,crane lifting weight: greater than or equal to 25 tons, can be thought of as chongqing steel structure.Steel weight of the

2, per square meter, less than or equal to 50 kg/M2, can be regarded as light steel structure.

3, the main components: steel plate thickness less than or equal to 10 mm, light steel structure.

This wall structure arrangement, can be effective and reliable delivery under vertical load, and the arrangement is convenient, but the wall structure cannot bear horizontal load.

3.3 Thermal insulation construction technology

Fill glass fiber between floor joists, minimize heat transfer through the floor;All interior wall posts are filled between the glass fiber, reduce the heat transfer between the household wall.

3.4 Building fire prevention technology

in order to achieve an hour fire prevention requirements, in the wall between the wall and floor joists between pillars fill glass fiber for fire prevention and heat transfer also play a positive role in protecting.

3.5 Building sound insulation technology

made the following structure: for the ledger wall with two wall columns with a gap between two walls;For the fixed plasterboard condole with small keel, with flexible structure that has a small slot cutting to effectively reduce the solid sound propagation between floors
